How to install DruCall
----------------------

a) set up a TURN server, e.g. use the one of these packages
   on Debian or Ubuntu:

     resiprocate-turn-server
         http://packages.debian.org/wheezy/resiprocate-turn-server

     rfc5766-turn-server
         http://packages.debian.org/sid/rfc5766-turn-server
        
     turnserver
         http://packages.debian.org/sid/turnserver

b) set up a SIP Proxy or PBX supporting SIP over WebSockets / WebRTC,
   for example:

     http://www.resiprocate.org/WebRTC_and_SIP_Over_WebSockets

     http://sip-router.org/docbook/sip-router/branch/master/modules/websocket/websocket.html

c) set up a user to receive calls, for example, using one of the online
   configurable SIP WebRTC demo apps:

     http://tryit.jssip.net/

   or install one of these apps to your own server (e.g. the Debian package
   jscommunicator-web-phone), and then go to
       http://your-server/jscommunicator-web-phone
   and log in to your SIP proxy.

d) unpack the modules:

    DruCall module into your Drupal 7 modules directory
    libraries API into your Drupal 7 modules directory

    Install the JsSIP and JSCommunicator modules from these two sites:

    https://github.com/opentelecoms-org/drupal-mod-jscommunicator/releases

    https://github.com/opentelecoms-org/drupal-mod-jssip

    and follow their instructions to install the JavaScript files themselves.

    To save time, you can do all of the above using the Debian packages:

       apt-get install drupal7-mod-jscommunicator

    For details, see:

    http://danielpocock.com/debian-solving-drupal-third-party-library-distribution

e) go to the Administration / Configuration / DruCall / Settings panel,

     http://your-drupal-site/admin/config/drucall/settings

f) set up all the necessary settings for your SIP Proxy/server and user

g) now go to
 
     http://your-drupal-site/drucall

   Click one of the buttons and make a call - easy
